outset,

I minor objects in View my invention conof the end sill sists of theparts and combination of parts as will be hereinafter more 'fullyysetout.

In the drawing, Figure 1 is an elevation ofa car. with my inventionattached. Fig. 2 1s a top plan view of the same. i i lrepresents the end"sill to which a plate 2is secured by any suitable means. The

plate 2 is provided with an undercut groove to slide in the 3 in one ofits faces and with studs or fulcrum points 4 and said fulcrum pointsbeing disposed in ditfereut horizontal'planes.

6 is a plate having shoulders 7, said plate and shoulders being mountedand adapted undercut groove 3 of the plate 2. i

8 is a fulcrum stud integral with the plate 6 upon which the operatinglever 9 is pivoted and secured. thereon by any suitable means. Theoperating lever 9 is provided with an arm 10 having an offset or clip 11on its extreme end.

1:2 is a lever pivoted upon the stud 8 at one end and adapted to restand be supported in the clip or offset 11. The extreme inner end of thelever 12 is adapted for engagement'with'the coupling pin or one of thelinks of a chain secured to the coupling pin as found most desirable. Itwill be noted that the lever 12 has a rearward extension 13 beyond thepivot stud 8 to a point beyond the fulcrum 5.

In operation if pressure is exerted downwardly upon the operating lever9, the inher end of the lever 12 is elevated through the medium of theclip or offset 11' of the operating lever 9, thereby elevating theuncoupling pin. If the outer end of the, op'

erating lever 9 is .pulled upward, then the arm 10 of the lever 9 iscaused to move downward until it 'coines'into contact with a fulcrum a;On continued upwardmove-x merit ot the outer end of the operating le-Speeifieation of Letters Patent.

ver 9 the lever is then fulcrumed on the fulcrurn 4 whereby the pivot 8with its plate 6 is caused to cut groove 3, which brings the rearwardextension 13 of the lever 12 into contact with the fulcrum 5. Acontinued upward movementof the operating lever throws the extreme innerend of the lever 12 upward by reason of the fact that said lever 12 isnow fulcrumed'on the fulcrum 5 and swings on thetpiivot 8 whereby theuncoupling is etec e slide upwardly in the under-- As changes may bemade in the minor details of construction without departing from thespirit of my invention, I do not wish to be understood aslimitinglmyselfto the de tails of construction shown.

Having thus described my invention what Iclaim is: p

1. A two-part uncoupling lever having a slidin .fulcrum.

12,. 11 .uncot1plinglever comprising two levers, a slidably mounted.shifting fulcrum and a fixed fulcrum for both levers; 4

3.- An uncoupling lever comprising a plate havin a dovetailed recess,studs on the face of sai plate on opposite sides of said recess and indifferent horizontal carried by said block, of a lever pivoted on oneend of the lever being longer than the other, the shorter end beingconstructed to engage one of the studs on said plate, a lip formed on"the shorter end of the lever, a second lever pivoted to said pivot pin,the longer arm of said second lever resting in said lip and constructedto engage the locking pin of a coupler, the shorter arm-adapted toengage one of the studs on said plate.

4. An uncoupling lever comprising a Jlate, two fulcra fixed on saidplate in difi erent horizontal planes, slidable fulcrum mounted on saidplate, an operating lever pivotally mounted on said slidable fulcrum, anarm extending beyond the slidable fulcrum and integral with theoperating lever, an uncoups ling lever pivotall v mounted at-a pointnear one end on the slidable fulcrum.
